The document compares the design of an Intze water tank using membrane design and continuity analysis methods. Membrane design assumes members act independently and are only subjected to direct stresses, while continuity analysis considers restraint at edges causing secondary stresses. For a 9 lakh liter tank, continuity analysis results in higher hoop forces, moments, and steel reinforcement compared to membrane design. A similar trend is seen for a 6 lakh liter tank, with continuity analysis giving higher stresses and reinforcement.
The document discusses reinforced concrete columns, including their functions, failure modes, classifications, and design considerations. Columns primarily resist axial compression but may also experience bending moments. They can fail due to compression, buckling, or a combination. Design depends on whether the column is short or slender, braced or unbraced. Reinforcement is designed based on the column's expected loads and dimensions using methods specified in design codes like BS 8110.
The document discusses composite construction using precast prestressed concrete beams and cast-in-situ concrete. It describes how the two elements act compositely after the in-situ concrete hardens. Composite beams can be constructed as either propped or unpropped. Propped construction involves supporting the precast beam during casting to relieve it of the wet concrete weight, while unpropped construction allows stresses to develop under self-weight. Design and analysis of composite beams involves calculating stresses and deflections considering composite action. Differential shrinkage between precast and in-situ concrete also induces stresses.

The document concludes that a pile cap distributes a building's load to piles to form a stable foundation on unstable soil. It acknowledges the guidance of professors in completing this project.
Columns are structural members that experience compression loads. They can buckle if loaded beyond their buckling (or critical) load. Short columns fail through crushing, while long columns fail through lateral buckling. The Euler formula calculates the buckling load of a long column based on its properties and end conditions. The Rankine-Gordon formula provides a more accurate calculation of buckling load that applies to all column types by accounting for both buckling and crushing. Proper design of columns involves ensuring they are loaded below their safe loads, which incorporate factors of safety applied to the theoretical buckling loads.

The document discusses the design of slender columns. It defines a slender column as having a slenderness ratio (length to least lateral dimension) greater than 12. Slender columns experience appreciable lateral deflection even under axial loads alone. The design of slender columns can be done using three methods - the strength reduction coefficient method, additional moment method, or moment magnification method. The document outlines the step-by-step procedure for designing a slender column using the additional moment method, which involves determining the effective length, initial moments, additional moments, total moments accounting for a reduction coefficient, and redesigning the column for combined axial load and bending.
Approximate analysis methods make simplifying assumptions to determine preliminary member forces and dimensions for indeterminate structures. Case 1 assumes diagonals cannot carry compression and shares shear between diagonals. Case 2 allows compression in diagonals. Portal and cantilever methods analyze frames by dividing into substructures at assumed hinge locations, solving each sequentially from top to bottom.
- There are four main methods to measure the load carrying capacity of piles: static methods, dynamic formulas, in-situ penetration tests, and pile load tests.
- The ultimate load capacity (Qu) of an individual pile or pile group equals the sum of the point resistance (Qp) at the pile tip and the shaft resistance (Qs) developed along the pile shaft through friction between the soil and pile.
- Meyerhof's method is commonly used to calculate Qp in sand based on the effective vertical pressure at the pile tip multiplied by the bearing capacity factor Nq.

Prestressed concrete is concrete that is placed under compression using tensioned steel strands, cables, or bars. This is done through either pre-tensioning or post-tensioning. In pre-tensioning, the steel components are tensioned before the concrete is poured, while in post-tensioning, the steel components are tensioned after the concrete has hardened. Prestressed concrete provides benefits over reinforced concrete like lower construction costs, thinner structural elements, and longer spans between supports.

Every manufacturing product requires cost efficient method and its variation in application maintaining its natural structure as well as assign service life keeping failure parameters in mind we are focused on our intention of designing, modifying and analyzing the jack model for actual loads for varying models on different applications. We are keen at making the scissor jack cost effective and at the same time maintaining its strength and life span. Also the new design that made by SOLIDWORKS software can be tested by ANSYS software. The overall strength of the jack is relatively more compared to commercially available screw jacks. Car jacks that are commercially available has some disadvantages such as required more energy to operate, not usable for aged people and cannot be used on the uneven and rough surface.

Parametric Study on Behaviour of Skewness on PSC Box Girder BridgesIRJET Journal
The document presents a parametric study on the behavior of skewed pre-stressed concrete box girder bridges. 50 bridge models with varying skew angles, spans, lanes, and section shapes are analyzed using finite element software to determine the impact on shear forces, bending moments, torsion, and displacement. The study finds that skewness has a negligible impact on bridges with skew angles up to 20 degrees but higher skew angles require more detailed analysis. Shear forces decrease slightly with increased skew angle while hogging moments increase and sagging moments decrease. Torsion is most significantly impacted, changing radically with higher skew angles. Bending moments also suddenly change at 60 degrees skew for 2-3 span bridges. Displacements are generally
Design, Simulation and Optimization of Multitubublar Rollcage of an All Terra...IRJET Journal
This document describes the design, simulation, and optimization of a multi-tubular rollcage for an all-terrain vehicle. The researchers created a 3D model of a rollcage in SOLIDWORKS and analyzed it using ANSYS to evaluate stress distribution and displacement under loading conditions. Their goal was to design a rollcage that provides structural strength and safety protection for the driver while keeping the overall weight low. They considered different pipe materials and cross-sections, selecting chrome molybdenum steel pipes with an outer diameter of 31.75mm and wall thickness of 1.65mm as the optimal design based on its high bending strength and stiffness but low weight.
This document provides a summary of the preface and introduction sections of the textbook "Reinforced Concrete: Mechanics and Design". The textbook covers the theory and design of reinforced concrete structures over multiple levels, starting with introductory concepts and progressing to more advanced topics. It emphasizes designing structures that can be safely constructed in a cost effective manner and provide long-term service. The analysis of flexural strength in beams is presented at a basic level, while more complex topics like column strength are at a higher level suitable for advanced students.
IRJET- Design and Modification in Clamping SystemIRJET Journal
The document describes the design and modification of a clamping system to allow adjustment of parts from 90 to 140 degrees. It aims to reduce rework, save labor during welding and cutting, and increase production rates. The system was designed based on a literature review of existing clamping systems and their limitations. Key components like the screw, nut, and base plate were modeled in CAD software. Testing showed the modified clamping system could accurately hold parts at varying angles from 90 to 140 degrees for machining, addressing limitations of prior clamping designs. This allows easier positioning of parts for welding and cutting tasks.
IRJET- Design and Analysis of Residential Multistory Building (G+5) by using ...IRJET Journal
This document describes the design and analysis of a residential multi-story building (G+5) using ETABS software. The building is designed using AutoCAD and ETABS to analyze stresses in slabs, beams, columns, floors, walls and footings. Load calculations are performed for dead loads, live loads, lateral loads, axial loads, and seismic or wind loads according to Indian codes. The analysis checks stresses and load capacities of the entire structural system, including reinforcement requirements for columns and staircases. Footings are designed based on soil bearing capacity. The results obtained from analyzing the building structure in ETABS are also discussed.
IRJET- Design and Development of Jig and Fixture for Tacho BracketIRJET Journal
This document describes the design and development of a new fixture for machining a Tacho Bracket component. The current process requires 5 setups on different machines, including VMC, RDM, and HMC machines. This leads to long cycle times and loading/unloading of the component between machines. The new fixture is designed to complete the required operations in 2 setups on HMC machines. It utilizes hydraulic clamping to reduce loading/unloading time. Analytical calculations and FE analysis show the new fixture design is capable of withstanding the cutting forces. The new process is expected to significantly reduce the cycle time for machining each component from 47 minutes to 34 minutes.

3. Introduction
Curved beams are used to support circular reservoir, curved balconies
and curved ramps.
In curved beams the centre of gravity of loads acting on a span lies
outside the lines joining supports.
This will cause torsional moments in addition to bending moment and
shear force.
Therefore one need to consider torsion reinforcement while designing
beam curved in plan.

11. Design Example
Determine the reinforcement required of a ring beam (Fig.6.16.3) of b =
400 mm, d = 650 mm, D = 700 mm and subjected to factored Mu = 200
kNm, factored Tu = 50 kNm and factored Vu = 100 kN. Use M 20 and Fe
415 for the design.

14. Comparison
• Software can design straight beam precisely and accuracy will be
similar to manual method but for curved beam software is unable to
give results similar to manual method.
• Besides % of steel in both results longitudinal reinforcement ,
transverse reinforcement and side face reinforcement is considered.
13/07/2019 VINAYAK SURESH PATIL 14
15. Conclusion
• In curved beam torsional reinforcement must be provided as torsional
moment are generated.
• Software can not provide precise design as torsional moments are not
considered properly.
• Use of IS 456 & manual design ensures safety as effect of both bending
& twisting moments are considered along with shear force.
•Aside from aesthetic view curved beam should be avoid as these are
not economical.
